LinuxBoot

LinuxBoot is the concept of using a Linux kernel and initramfs as a bootloader. The linuxboot repository contains a build system implementing LinuxBoot primarily targeting servers and PCs, which started as NERF in January 2017 at Google. Why? Improves boot reliability by replacing lightly-tested firmware drivers with hardened Linux drivers. Improves boot time by removing unnecessary code. Typically makes boot 20 times faster. Allows customization of the initrd runtime to support site-specific needs (both device drivers as well as custom executables). Proven approach for almost 20 years in military, consumer electronics, and supercomputing systems – wherever reliability and performance are paramount. LinuxBoot Book 📖 The official documentation for LinuxBoot is the LinuxBoot Book, where you can find information on how LinuxBoot works, how to build the various flavours (e.g. coreboot/LinuxBoot or UEFI PEI/LinuxBoot), the u-root ramfs builder, etc.
